Build 267 is a FULL install ie NO need to install any
other version first. Your existing Bandplans and Registry settings
should be preserved if upgrading from an earlier version.

To Install, just Download and Run.

Build 267 has improved support for the Fifi SDR -
includes the FiFi Extio support, includes support for Bonito RJ10, and
support for a fixed 455 KHz IQ down converter for pan-adaptor
usage with conventional radios, eg RA1792. If you're not experiencing
any problems, and/or don't need the extra support, then you can safely
ignore Build 267.

Build
256

Build 256 is a FULL install ie NO need to install any
other version first. Your existing Bandplans
and
Registry settings should be preserved.

Apart from the items above, there have also been
numerous little fixes including making the G8JCFSDR easier to install
onto Windows 7, and a general tidy up of the code.

Build 243

Build 243 is an Update to the .EXE. You must have
previously
installed Build 231 or Build 232 or Build 234 for this Update to work.

To Install, download, unzip, and copy G8JCFSDR_243.EXE
into the
same directory where you currently have G8JCFSDR stored.
1) Rename the existing G8JCFSDR.EXE to something
else, eg
G8JCFSDR_231.EXE
2) Rename G8JCFSDR_243.EXE to G8JCFSDR.EXE
3) Run G8JCFSDR from the Start Menu

Build 234 is an Update to the .EXE. You must have
previously
installed Build 231 or Build 232 for this Update to work.

To Install, download, unzip, and copy G8JCFSDR_234.EXE
into the
same directory where you currently have G8JCFSDR stored.
1) Rename the existing G8JCFSDR.EXE to something
else, eg
G8JCFSDR_231.EXE
2) Rename G8JCFSDR_234.EXE to G8JCFSDR.EXE
3) Run G8JCFSDR from the Start Menu

Fixes & Features

1) Support for the Pappradio SDR
hardware
using the EXTIO_*.DLL mechanism
Download and install the
Pappradio
extio files from www.pappradio.de
,
configure the COM port, then copy extio_pappradio.dll, config.ini &
fqdata.dat into the same directory as the G8JCFSDR

2) Elektor SDR boards: Previous
builds of
G8JCFSDR required the L<->R checkbox to be checked for Ver 1.1
Elektor
boards. In build 234, the default is that v 1.1 boards do NOT need the
L<->R checkbox ticked - Elektor retracked the board so that the
3.5mm IF
output jack fitted correctly on the component side of the board and in
process
corrected the IQ output wiring. Users with the V1.0 Elektor boards will
now need
to check the L<->R checkbox. Remember to set -P in the DREAM
configuration
parameters for correct operation with DREAM.EXE

3) The CB bandplan should now work
properly

Build 231

Build 231 is a full Install. Your existing Bandplans
and
Registry settings should be preserved.

1) Alternative Spectrum Smoothing Algorithm.
Build
231 has a
new alternative Spectrum smoothing algorithm which is slightly less CPU
intensive although I personally feel that the display is not as nice as
the
current smoothing algorithm - to change Spectrum smoothing algorithm go
into
Config, then under the Spectrum Display tab select A (Current
algorithm) or B.

2) How to use Slide and Tune on the Spectrum Display.
a) Select Pre-Demod as the
source,
turn on Show Filter
b) Left click over the
spectrum will
retune the Hardware VFO
c) Right click over the
spectrum will
retune the internal s/w NCO or BFO to demodulate the signal
d) Right Click over the
Slide 'n Tune
Thumb above the Spectrum will set the s/w NCO to default, ie at the
12KHz
position on the LHS of the display, 3 divisions from the left hand
edge. Do this
when receiving DRM signals so that the DRM signal is at 12KHz as
expected by
DREAM.
e) Left Click over the Slide
'n Tune
Thumb above the Spectrum will retune the s/w NCO to the mouse position
to
demodulate the signal
f) The buttons above the
Spectrum
will retune the h/w VFO up or down by 48Khz for IQ Rxs such as the
Elektor SDR,
and +24 or -24 for
single ended Rxs such as the DRT1 and DRB32.

3) 10KHz-30MHz Tuning Range.Tuning range has now been extended
down to
10KHz, so reception of MSF on 60KHz and DCF on 77KHz is now possible -
the LMS
noise reducer really helps bring out the signal

4) 48KHz Up Down Quick Tune. There are Up and Down buttons on
the
Spectrum Display enabling a very quick +48KHz or -48KHz frequency shift
for band
scanning for activity

5) On the spectrum display, a Right click over a signal, tunes in that
signal,
but doesn't change the h/w VFO

6) The spectrum display filter option behaves more as expected, ie
there were
lots of bugs before !!

7) LMS Adaptive Noise Reduction - hover over
the ON
checkbox for config instructions - Also, the LMS noise blanker should
retain its
settings between runs but more to do in this area. I've found settings
of
MU=0.00381, Leakage=0.99999, Taps=49, DelayLine=0, Type=B,
NormaliseGain=True to
work quite well.

11) 50% More Presets. 6 More presets per band,
ie 18 up
from 12 in earlier builds

12) Better IQ Balancing. New algorithm for
balancing I
& Q channels - you should be able to reduce the image into the
noise floor,
ie at least -60dB without too much fiddling

Build 216

Installation : Download and Unzip Build 216
into the same
directory where you have installed Build 205. Then rename G8JCFSDR.EXE
to
G8JCFSDR_205.EXE and then rename G8JCFSDR_216.EXE to G8JCFSDR.EXE

1) Keypad for direct frequency entry  both
onscreen and
real keyboard work. To enter frequencies using the new keypad feature:

a) click the SET button just under the main 7 Seg display and the
keypad will pop up.
b) click on the digit button using the mouse to enter a frequency or
type in the frequency using the PCs keyboard. You can enter a
frequency in several ways:

i) Enter the frequency in MHz and press the MHz button or type
the letter M (case insensitive), eg if you enter 10M then the frequency
>will be set to 10 MHz. For example, if you enter 10.125M then the
frequency will be set to 10.125 MHz.
ii) Enter the frequency in kHz and press the kHz button or type the
letter K (case insensitive), e.g. if you enter 5050K then the frequency
will be set to 5050 kHz, e.g. if you enter 5050.010K then the frequency
will be set to 5.050010 MHz.
iii) Enter the frequency in Hz and press the Hz button or type the
letter H (case insensitive).

c) To dismiss or close the keypad, either click on the RED X in
the >top right hand side, or press the ESC key on the keyboard  you
can also click the SET button when the keypad is onscreen and that will
dismiss it as well.
d) To clear a frequency click on the C button or type C on the
>keyboard  a backspace will be added in the next release
e) To position the keypad, press and hold down the left mouse button
the blue strip at the top of the keypad window and move the keypad to
where you want it. You can also move the keypad window using the same
technique over a bare area of the keypad window.

2) Drag 'n Tune now more fully implemented -
still more to
do!

Right mouse click will tune the s/w NCO, whereas
left
click will tune the h/w VFO. Also see the + - buttons at top Right Hand
of scope
display.

5) Changed the Hamlib code from using the VFO_CURRENT to
using VFO_A,
this may help with the DWT, but it may also stop working with other
rigs like
the DRT1 - I haven't got my DRT1 to hand right now, so if someone has a
DRT1 I
would really appreciate a report if the DRT1 in Hamlib mode is still
working 
and if anyone has a Coding Technologies:DWT, then Peter would also
really
appreciate a report of success or not.

6) More settings persisted between runs

7) Improved the Experimental NR,
around 12%
seems to work best, click "DYN", and Click "Music".

Build 205

1) Full install - no need to install
build 147
first
2) OS Restriction removed, so it should install on
VISTA, but
see VISTA & Win 7 Issues
for VISTA & Win 7
specific
workarounds
3) Bit-bang mode over FTDI FT232 chips has been made
much
faster, this is most noticeable when using the NTI DRB30, the DRTI and
the
Elektor 3/04
4) Elektor 3/04 over FTDI US232C converter now works !
5) B/W display on the Spectrum Analyser now shows the
correct
width - Default Colour changed to Gray
6) There is a dead patch on Long Wave between
175~188KHz in
build 198, in this build, you should be able to tune in 1KHz steps
right across
LW band
7) Have added the other inputs on the Elektor IQ/SDR,
Aux1,
Aux2, Aux3
8) The extended panel for Elektor IQ/SDR support is
only
visible when Elektor IQ/SDR is selected, for all other rxs this panel
is hidden
and the G8JCFSDR display is re-sized accordingly
9) When the RX is off, U can adjust the scope display
controls, eg Hz/Div and adjust the spectrum display - useful for
examining
signals in depth
10) New Quick Start Guide with Soundcard IQ checking
instructions
11) HamLib DLLS now available as an install program

Full support for IQ down-converters, eg Soft Rock, Funk
Amateur,
& ELEXS AD9835+CY27EE16 combo. Also support for an AD9850 LO
followed
by the classic 74AC74 divide by 4 arrangement.
Select Model number in Config from drop down list. "IQ, Crystal
Controlled" is a generic model covering all Xtal controlled IQ
downconverters. Set the Xtal frequency.
Build 168 only provides 24KHz of spectrum display at a time. To
tune/view the
'upper part', click on "IQ Upper" checkbox

New/Fixes - (Build 147)

1) Change any
colours
on the SDR - See Controls TAB in configuration
2) Mirror the Notch filter,
ie see
what the notch filter is cutting out
3) Start of IQ downconverter
support -
see Config - General Tab, Select IQ Xtal Rx
4) Fixed incorrect detection
of iSPL
5) Lots of small stuff all
over the
place

Tips:-
a) Press CTRL when over a
preset to
toggle the preset detailed display
b) Right mouse click over
scrollable
labels to reset the control to its default value
c) Tune the SDR by
left-clicking on a
signal over the Spectrum display - tunes to the nearest KHz
d) Single left mouse click
over a
digit on the Tuned Frequency display locks the tune rate to that digit
- double
click gives free-tuning mode
e) Single left mouse click
over the
Virtual Tuning Dial cycles through shaft encoder tuning rates
f) Shift+Left Click on
a preset
stores the SDR's current values to that preset - also try Right Click
over the
preset
